My Quest to 5.0Ghz.

post #1 of 25
Thread Starter 
I've got this 2600K a few months ago and so far I'm 4.8Ghz @ 1.38V but I can't get any further. I'm not sure what is going wrong here.

I've pushed it to 1.41 trying for 4.9Ghz but it failed instantly on Prime. Ive never touched the Vcore it's on auto or 300. I've seen people set it to 350 but I'm not to sure what exactly it does so I haven messed with it. Also I have never played around too much with offset mode I've kept it on manual. Are there advantages to offset mode?

Can you post all of your current settings, especially making sure to post the ones you have altered from default?

Also, using a VRM Fixed Frequency Mode of 350 is supposed to be "best for sustaining stability at multis of 48x or above. This is key especially for running unrealistic loading testing such as prime or linx" (source).

You'll have to push your Vcore even higher than 1.41 to get 5.0 GHz..

To get 5 GHz you'll probably need to play with other settings such as DLL voltage, load-line calibration, etc.

But yeah post all your settings and we can further help you out.

Lowest Vcore I can do is 1.44 during load @ 5Ghz. So yeah, you probably gotta go higher. I wasn't able to do 4.9Ghz without goin with at least 1.41v.

You will more than likely need PLL Overvolt enabled. That setting is usually overlooked.

That setting is actually only needed if a system cannot boot at a high multiplier after exhausting all other options to try and get it to boot at that multiplier (so, it's not intended to make a system stable - it's to get it to boot after trying everything else). Right now, his system is booting but it's failing Prime95.

I have done hundreds of hours in prime with my chip testing various things, PLL overvolt was actually needed on many occasions to stabalize certain clocks, not just boot into windows. This has been common with other users i have helped, despite what the Asus Hardforum guide says, it will on occasion stabalize certain clocks and not just help to boot into windows.

You ain't trying until you drop 1.6 through the chip.

That's how real men like me do it.

It also let me get to 5.4 ghz
